rear of the duct to direct the flow of air and the direction of the subsequent momentum transfer
from the air to the craft. The driver controls the movement of the rudders through a joystick
located in the front of the craft. A throttle on the engine situated next to the driver allows him
to vary the speed of the craft, allowing for a smaller radius of turning once proper driving
techniques are mastered.

Post-war progress:

When the war ended a number of groups took up development of air-cushion vehicles again. The

the surface below, and contained within a skirt. Because they are supported by a cushion of air,
hovercraft are unique among all forms of ground transportation in their ability to travel equally
well over land, ice, and water.
The main parts of a hovercraft are:
Skirt Hull
Lift Fan Thurst Fan
Basic Design:
The lifting motion is controlled by a fan or fans so that an air gap can be formed such separation
between the bottom of the hovercraft and the ground provides a motion platform, on which the
friction force between the hovercraft and the ground reduces to a very small amount Since ..................[:=> Show Contents <=:]

n the hovercraft is finally able to move it will most definitely require steering capabilities. This
is achieved through the use of rudders. These rudders can be controlled by a variety of devices
including computers. Rudders cannot be too heavy otherwise they will weigh down the craft because
they are located very close to the motor. The shape of the rudder dictates how well it will be able
to move air.
When riding a hovercraft the natural state of motion is easily seen to be constant vector velocity
with a constant rate of rotation. A sloping floor will definitely change your velocity vect..................[:=> Show Contents <=:]

ess the air. That use of electricity means there is some amount of pollution produced somewhere
else. Some of the leftover heat in the engine's exhaust is cycled back through the engine to the
economizer, which preheats the nitrogen before it enters the heat exchanger, increasing efficiency.
Two fans at the rear of the vehicle draw in air through the heat exchanger to enhance the transfer
of heat to the liquid nitrogen.

nd, water, ice etc. Their main area of applications are in military vehicles, helicopters and where
transportation using wheeled or tracked vehicles are impossible. Air cushion vehicle (ACV) is a
craft that travels on a layer of compressed air just above any kind of surface - land, water, ice,
sand, mud etc. The compressed air serves as an invisible cushion that eliminates almost all friction
between the vehicle and the surface. Air cushion vehicles are also known as Hovercraft. They can
carry both passenger and freight. Some air cushion vehicles can travel as fast as 480 km per hour.In
